Amandla centrifugal: kuyini futhi asebenze kanjani?

Njengoba yaziwa, iyiphi isici umzimba wenyama silondoloze esimweni saso ukuphumula noma iyunifomu ezinyakazayo rectilinear nje ngeke Awenzanga nomthelela kulo kwabavela ngaphandle. Amandla centrifugal - lena lutho kodwa ibonakalisa jikelele umthetho inertia. Ekuphileni kwethu, butholakala ngokuvamile ukuze sikwazi cishe awuboni ke futhi osabela ngayo kukho kuzinga enganakile.

Umcabango

Amandla centrifugal - uhlobo nomthelela ngaleso sikhathi ngokomzimba ekuqineni izibopho zayo nenkululeko ukunyakaza futhi kukwenze ukuhambisa curvilinearly isihlobo ngibopha umzimba wakhe. Ngenxa vector displacement we umzimba sishintsha njalo, ngisho esimweni lapho ijubane layo uma igijima ngokuphelele uhlala ingashintshiwe, ukubaluleka ukusheshisa ayilingani zero. Ngakho-ke, ngenxa yomthetho Newton yesibili, owenza izindlela ukwencika amandla phezu mass nokusheshisa yomzimba, futhi kukhona amandla centrifugal. Manje, khumbulani umthetho wesithathu physics esidumile British. Ngokusho kwakhe ngokwesimo amandla akhona ngababili, futhi ngokunjalo, kumele ibutho centrifugal kuhambisana okuthile. Eqinisweni, kumelwe ukuba kukhona okuthile oqhubeka umzimba endleleni yayo lwalugobile! Kuyinto, esihambisana le ukuphotha centrifugal ku into njengoba centripetal amandla izenzo. Umehluko phakathi kwabo ukuthi wangaphambili unamathele umzimba, kanti eyesibili - ukuze uxhumano yakhe iphuzu ezungeze okuyinto Ukujikeleza kwenzeka.

Lapho kubonakala amandla centrifugal

Kufanele unikezele ngezinsizakalo a isisindo encane esandleni ukuthi sinamathela Twine ngokushesha uqala ukuzizwa ukungezwani enezintambo. Ukube bezingekho amabutho nokunwebeka, ithonya amandla centrifugal eyayiyoholela uqhekeko intambo. Njalo siya endleleni isiyingi (ibhayisikili, imoto, tram, njll), thina sicindezelwe kolunye uhlangothi kusukela isiqondiso ukuzungeza. Ngakho-ke, ngesivinini amathrekhi ezindaweni Curves Friend endleleni has a ukuthambekela ekhethekile ukuze udlulisele ukuzinza enkulu ukuncintisana bamabhayisikili abaphambili. Ake sicabangele esinye isibonelo ezithakazelisayo. Ngenxa iplanethi yethu uzungeza kuma-axis awo, amandla centrifugal enza yiziphi izinto, okuyinto zitholakala phezulu. Ngenxa yalokho, zonke izinto ube lula. Uma uthatha isisindo we 1kg futhi asisuse isigxobo nenkabazwe, isisindo sayo kuyehla 5 amagremu. Njengoba imigomo ubala, lesi simo sibonakala asihlobene. Nokho, nge isisindo okwandayo lo mehluko kwandisa. Ngokwesibonelo, esitimela umusi efika e-Odessa kusuka Arkhangelsk, bekuyoba lula ku kg 60, futhi yempi nesisindo esingaphezu kwamathani 20,000, wasuka White Yasolwandle Eya E woLwandle Olumnyama, kuyoba lula kakhulu ngendlela 80 amathani! Kungani lokhu kwakwenzeka? Ngoba amandla centrifugal ezivezwa ukujikeleza iplanethi yethu, ivame ukuba asakaze ebusweni bomhlaba, konke kuba. Yini enquma ukubaluleka ibutho centrifugal? Nalapha futhi, khumbula kokubusa Newton yesibili. Umngcele we-lokuqala ethonya ubukhulu bale amandla centrifugal Yiqiniso, kuyinto nenqwaba umzimba ligijima. A Ipharamitha yesibili - ukusheshisa, okuyinto in motion curvilinear sincike Isivinini ukujikeleza kanye engaba umzimba ezichazwe. Lobu buhlobo ingaboniswa ngendlela ifomula: a = v ² / R. Ingabe etholwe: F = m * v ² / R. Ososayensi balinganisela ukuthi uma Earth wethu ujikeleza kanye njalo ngemva 17 ngokushesha bese enkabazwe kungaba isisindo, sengathi kwaba nombhikisho ephelele yafezwa ihora elilodwa nje, kwesisindo somzimba laliyozwiwa hhayi kuphela yenkabazwe, kodwa kuzo zonke izilwandle nakho emazweni, okuyizinto eseduze nale ndlela.
